This printer features a built-in spooler with four independent filament bays. This means that The Indymaker can print objects with four different materials/colors. A computer-controlled filament switch integrates with the spooling bay to deliver your choice of color, when and where its needed.
The first kit was built early in 2011 and the final design is now a Kickstarter project. They are in need of some extra pledges to get their project funded so if you believe in this printer, go visit their page on Kickstarter and give them your support!
